GURBENT-MO'JJOR.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed December 10,1907. Serial No. 405,953.

adapted for use upon the bottom of streams .and it will also be readily understood that at and the object of the invention is a motor of this kind which will be protected against any material floating in the stream and which can be operated during the winter when the surface of the stream is frozen equally as well as during other seasons of the year.

The invention consists of the novel features of construction hereinafter setv forth,

pointed out in the claim and shown in the v drawings, in which- Figure 1 is a perspective view of the base and protecting grille work; Fig. 2is a lon itudinal section through the base and grille, the motor beingshown in elevation, a small portion being broken away; Fig. 3 is an end view looking up stream; Fig. 4 is a detail perspective view of a portion of the blades and. a shaft. I

In'these drawings A re, resents a suitable base of sufiicientsize anti Weight to anchor it securely in place upon the bed of a stream. Upon this base is mounted a frame of grille work A, the up stream end of which tapers to a point. U on the base A areplaced standards B a jacent each end and upon these standards is journaled a rotatable shaft 0. At each end portion of the shaft are arran ed two oppositely extending and opposite y curved arms C. These arms are secured to blades D which are twisted'so as to encircle spirally the shaft C, the two blades combined forming a screw against which the force of the current passing through the grille A is expended. Upon the down-stream end of the shaft D is mounted a wheel E having curved and angled blades E and also provided upon its rim with beveled cog teeth E which mesh with a bev-,

eled pinion F carried at an end of a shaft F. The operation of the device will be-obvious the shore end of the shaft F anyv coupling means may be employed which may be found-necessary to connect said shaft to the shaft or machinery to be driven. It will also be obvious that a number of these motors maybe connected to other so as to increase.

having a pointed end portion,'a shaft 1ongitudinally arranged in said rille and supported from the base, a whee fixed upon said shaft, said wheel having beveled gear in :th

jects,

thereon, fan blades arranged within the' wheel, spirally arranged blades carried by the shaft, a second shaft at right angles to the first mentioned shaft, and a beveled pmion meshing with the beveled. teeth of the wheel.
